I know blizz probably won't change this or really any other card unless it's completely insane (Dr.Six). But one thing blizzard can and will eventually do is add new cards. I'd really like to see some cards that make mech-druid viable, i mean already most druids run piloted shredder. And I don't want mech-druid to be another silly aggro mech deck, I'd like a much more control and tempo based deck for one of my fav classes. (A 6/7 would probably still be better though)

Yeah, it's not a constructed card for sure. It just doesn't provide enough value in the most common cases to justify the mana cost. Force of Nature is like a 6-attack creature with charge or can even 3-for-1 an aggro deck if it comes to that. Or it's a combo-winning finisher. That kind of flexibility, speed, power and value far surpasses Mech-Bear-Cat unfortunately.

This card is much better then the legendary they just came out with. lets just say you only get one spare part you have two copy's of it making it close to as good as Savannah Highmane that might be a bit of an over exaggeration but still a great card.

I actually prefer a 6/6 than a 7/6 but you can always use Reversing Switch or Crazed Alchemist to make it a Boulderfist Ogre with a bonus. Besides, only 7 cards, Gorehowl, Fireball, Polymorth, Hex, Big Game Hunter, Assassinate and Shadow Word: Death can kill it right away so still pretty decent. It should be good in Control Druid. Will probably be good with Madder Bomber, Unstable Ghoul and Mad Bomber for draw. The spare parts can be useful to buff say Ironbark Protector or Cenarius.

So, are you saying this card is immune to Naturalize, Poison Seeds, Siphon Soul, and Twisting Nether, not to mention the numerous cards that can kill this with just a little bit of luck, such as Vaporize, Deadly Shot, and Ragnaros. Then there's the cards that should be able to kill this with just a little bit of help, such as Execute, Patient Assassin, Emperor Cobra, Maexxna (granted no one plays those last 3).
